About the National Data
Data Source: American Housing Survey (AHS), HUD & Census
Baseline: 51.3 percent of occupied homes and residential buildings had a no-step entrance as a visitable feature in 2017
Target: 53.1 percent
The AHS is conducted by the Census Bureau through 12 regional offices using telephone and personal visit interviews. The AHS conducts two surveys: a national survey and a metropolitan survey. The national survey gathers information on housing throughout the country and is in the field in odd-numbered years. The metropolitan survey covers households in seven metropolitan areas. A sample of housing units is selected from the decennial survey. These are updated by a sample of addresses obtained from building permits to include housing units constructed since the sample was selected. The same housing units are resurveyed on a regular basis, recording changes in characteristics, adding and deleting units when applicable. The Bureau staff make personal visits if the housing unit is new to the AHS sample; if the household living in the sampled unit has changed since the previous interview; or if the period between the interviews exceeds several years, which is the case for the metropolitan areas.
